What are the famous commercial war cases in history?

In Hong Kong in the 1970s, it was asserted that whoever owned Wharf would master most of the cargo handling, storage and transportation and cross-sea ferries in Hong Kong. This statement is correct. At that time, Wharf's industries included most docks and warehouses in Tsim Sha Tsui, Kowloon, New Territories and Hong Kong Island, as well as hotels, buildings and trams. Wharf's rich resources made all businessmen on Hong Kong Island salivate at that time. This wharf commercial war is a classic commercial war.
